HENRY E. JOHNSON, or OMAHA, NEBRASKA.

' Be it known that I, HENRY E.Jo1ii\isoiv, a citizen' of the United States, residing at Omaha, in the county of Douglas and State .of Nebraska, have invented certain new and vusctul Improvements in Trucks, of

isiniportant'that all oft the trucks thus'eon-A neeted rmay move substantially' in thesame curved -line or circle traversed'by the fore.-v As the Circle than the foremost truck, when they are connected end to end and an ,attempt is made to move them upon regula; curves, for the reason that the angle ofthe front and rear axle of each truck, to the longitudinal axis of the truck, will not` be uniform. By employing theherein describedtruoks, an operator,` by use ofthe tongue, may vcause the foremost one to move upon any desired` curve or curves, and the other trucks, connected and drawn therewith, willI all describe the same curves'; and this is of often necessary to move around obstructions in narrow, sinuousl passageways in the operation of handlingor moving freight.vv The invention alsohas reference to a conve-nient means for connecting the trucks, andtothe mountings-of the tongues. K

lVith 'these objects in view and others to be mentioned, the invention consists' of the `novel construction, combination and ar rangement of parts as described herein and claimed, and asV illustrated in the aceom- Figure l is a plan View showing thelower parts of a truck, the relative position or outj li'ne of the platform being indica-ted by broken lines. Fig. 2is-a side view ofthe truck, the platformv being in sect-ion.' Fig.

'is an enlarged detail showing-` a part oi a guide iii longitudinal section, the connected 'reaches being in transverse section.I Fig. y5 1s an enlarged, broken view, being a -detailrelating to Fig. 1, to clearly show a part of a guide and the connected reaches. referring now to the`drawing`for a niore particular description', numeral 5 indicates.

the front axle and 6 the rear axle of a truck, and upon the upper side of each` axle is dis'- .posedand suitably secured' the horizontal,

lower member'a of a 'fifth wheel 7, the upper meinberb of each fifth wheel being seated upon the lower member a and rigidly secured'to the platform by means of brackets 8.

, At 9 Vand 10 are indicated, respectively,

the front hounds and'rear hounds. of thel truck, each bei-ng substantially of tI-shape, and having curved end-portionslc conforming to the curvature of and' adapted'lto be secured upon the lowerffaee Vof the lower member a .of a 'fifth wheel, itsl terminals being secured lupon the axle by means of vboltsd',I 'and by means ofsaid bolts, mem-.

bers a are-rigidlysecured tothe axle.

Pivotally mountedl between the parallel arms of the fronthounds,'by means ofone' of bolts e is atongue llwhieh is normally siistained in an upright position by means' of a spring 12'; and at 12 are indicated devis-members which project outwardly from the front land `rear hounds, their mountings being uponbolts e. The clevismenibers are provided, betweentheir ends,

with transverse slots .14 which open upon their lower sides or edges, and at 15 are inl 'dieated lugs or stops which project outwardly. from` the sides of the hounds. Each elevisis free to he 'swung upwardly, and it .may be swung downwardlyl until the upper wall of its slot 14 engages a lug 15 as sliown in Fig. 2,'so that. while in these inclined positions, the adjacent clevises of two trucks may. be 'conveniently connected when it desired to move several trucks arranged as a train.

l OT) A't l16 and 17 are indicated levers, links or l reach members. The reach niember 16 Ais disposed at right angles to the front axle 5;

it is formed with a longitudinal slot 18 (Fig.

5.) and has a part-which extends below the axle 5 to be rigidly secured by any suitable means to the lower member a. The lever or reach 17 has a part disposed below the rear axle G to be rigidly secured to the lower member a thereof.A It is formed with a longitudinals'lot 19, and is disposed at right angles to said rear axle.

At 20 is indicated a horizontal guide or trackway, having parallel, upset edges or anges f. It is disposed midway between bolt-apertures 21 of the fifth wheels, transversely of the `platform' 22 and suitably secured at its ends to the platform by means of hangers or brackets 23. Disposed i'n slots 18 and 19 of the reaches and engaging in the trackway 20, is lug, pivot-pin or rider 24.

Any suitable king-bolts (not shown) may be employed and seated in apertures 21 for connecting the members a and b of each fifth wheel at their centers, so that these-members may swing in opposite d'rections; and an opera-tor, by use of the tonue 11 may manually control the swinging movements of the front axle. y

During operation, when the front axle is disposed at right angles to the longitudinal axis of the truck, the movement of said truck, of course, will be in a straight line; and when it is desired to move it upon a curve, the operator, byuse of the ole or tongue 11, may change the angle of t e axle 5, and this change will cause the reach 16 to swing truck. The swinging movement of reach 16 will causea swinging movement of reach 17, since the lug 24 engages the trackway 20. and engages within the slotsjof the reaches; and on account of the arrangement of the parts mentioned, while the rear axle will be swung -reversely to the movement of the front axle, both of the axles will be maintained at an equal angle, lug 24 sliding in the trackway 20, the reaches being supported by said trackway, the slo-ts 18 and 19 being engaged bythe lug and permittingvlongitudinal sliding movements of the reaches with reference to the connecting-lug, while tho'axles are performing their swinging movements. 1t will thus be seen that the angle of movement of one axle may be controlled by the movement of the other axle; and .by reason of the construction, the angles in which the axles of a'truir are disposed, with reference to the longitu `nal axis of the truck or the transverse tracliway 20, are always equal. Since the tongues 11'are supported in an upright position bymeans of springs 12',A they will not be obtrusive when; several of these trucks are connected end to end as shown in Fig. lVhen disposed in this manner lo form a train, the clevis at the end of one truck may be swung upwardly to lie upon the cle-vis of an adjacent truck, and may be connected by a pin 25.

1n practice, for drawing a train of these platform,

horizontally and transversely of the4 a lever rigid with and trucks upon curves, the operator, by use of the tongue of the foremost truck, may have a control to move it upon any desired curve. Since the rear axle of the foremost truck will be swung under control of the front axle, as described, it is obvious that the front axle of the truck which is connected to said rear axle will also be swung, with the result that all of the trucks, thus connected, will move upon the same curve, substantially', as the foremost truck; andthis is of great advantage for the handling of freight in warehouses where Ait is desired to move the train in cross-passageways, as vfirst mentioned.

While the length of trackway 20 is shown to be substantially equal to the width of the and 'therefore would permit swinging movements of the axles in an are of forty five degrees, or substantially so, the trackway may have .a length considerably less than shown, since a swinging movement for these axles of ten or fifteen degrees is all that is usually required.

Having fully explained my invention, what I claim and desire to secure by-Letters Patent is,-

1. A truck comprising, in combination `with a body, front and rear axles arranged to have horizontal swinging movement, a transverse trackway of channel form secured to said body between said axles, a lever rigid with and projecting rearwardly from the front axle, a lever rigid with and projecting forwardl from the rear axle, said levers having overlappingends having elongated V`slots formed directly therein, a pivot member traversing the slots of'both of said levers and engaging in and being guided by said traclcway, and a tongue for shifting said front axle.

2. A truck, comprising in combination with a body, front, and rear axles, arranged td have horizontal swinging movement, a transverse trackway 'of U,shape in cross section secured lto said body between said axles, projecting rearwardly from the front axle, a lever rigid with and projecting forwardly' from the rear axle, said levers having overlapping ends which overlie and rest upon said trackway and have elongated slots formed longitudinally therein, and a pivot member traversing the slots of both levers and depending into and being guided by said tracltway.

In testimony whereof 1 have aliixed my signature in presence of two witnesses.
